PRODUCT DESCRIPTION

Lab: Determining the Composition of a Hydrate

For students in Grades 8-12.

INTRODUCTION:
Hydrates are ionic compounds that have a number of water molecules attached as part of their structure. The water is present in a definite and consistent ratio. When hydrates are heated, the water is released from the compound as water vapor.

In this lab, the student will determine the percentage of water in the hydrate by comparing the mass of the hydrate to the mass of the anhydrous salt. The hydrate being used in this experiment is copper (II) sulfate “x”hydrate. When heated, the copper sulfate will lose the water and turn from a blue color to a white color.

PURPOSE:
1. To determine the percentage of water in a hydrate.
2. To determine the correct formula of copper (II) sulfate hydrate.
